Clay Buchholz has thrown just 11 2/3 innings since May 22 and hasn’t thrown a pitch in a major league game since June 8. There is no end in sight to the wait for the Sox top starting pitcher to return, and those anticipating his return received grim news today, as the Red Sox may be sending Buchholz to Dr. James Andrews to receive a second opinion on his shoulder. “Anytime you hear the name Dr. James Andrews connected to a pitcher, it gives you pause,” said Red Sox insider Sean McAdam, “because he is one of the most noted orthopedic surgeons in the country.”
